Title: Improvements in screw threading dies
IPC: B23G5/12
Filed: 1938-04-04
Abstract: 498,727. Self - opening die - heads. FAIRWEATHER, H. G. C. (National Acme Co.) April 4, 1938, No. 10337. [Class 83 (iii)] A screwing die-head has a body carrying radially movable chasers which are adjusted during operation to cut a tapered thread by means of interlocking cam means carried by an axially slidable sleeve and a rotatable sleeve, the latter being rotated by axial movement of a work-engaging member within the rotatable sleeve. The die-head comprises a body 5 provided with radial guides for the carriers 3 of circular chasers 2 and secured to a sleeve 6 having an end flange 6<1>. A member 8 is slidable within the sleeve 6 and has keys 16 thereon engaging axial keyways 18 in the sleeve and a guiding spigot 9. Rollers 17 are attached to the keys 16 and engage helical slots 18<1> in a sleeve 7 rotatable on the sleeve 6 and located axially by a flange 32 thereon engaging diametrically opposed blocks 24 sliding radially in slots in the flange 6<1> and normally pressed outwards by springs. Rollers 19 are attached to the sleeve 7 and engage cam slots 20 in members attached to the axially sliding flange 10 which carries bevelled guides 11 for actuating the die-carriers 3. A spigot 13 is rotatably mounted on the member 8 by means of an antifriction bearing 12 and is provided with interchangeable discs 14, 15 for engaging the end of the work a being screwed, the different sized discs corresponding to work of different diameters as shown by full and dotted lines in the Figure. In operation, as the die-head moves axially relatively to the work the latter meets one of the discs 14, 15 and holds the member 8 stationary whilst the remainder of the head continues its movement. The rollers 17 ride along the slots 18<1> to rotate the sleeve 7, and the latter, through its rollers 19 and the cam slots 20 withdraws the flange 10 to withdraw the chasers progressively from the work and produce a tapered thread. Springs 21 and tension springs connecting the fiange 10 to the flange 6<1> assist the retraction of the flange 10 and maintain the cams 20 in contact with the rollers 19. When the desired length of thread has been cut, diametrically opposed wedges 22 on the member 8 engage rollers on the blocks 24 to cam these inwards and release the flange 32 whereupon the springs withdraw the sleeves 6, 7 and the flange 10 axially to open the head. A stop 30 on the flange 6<1> limits the rearward movement of the sleeve 7 and the head is re-set by means of a handle on the sleeve 7. The diameter of cut is adjusted by screwing the flange 32 along the sleeve 7 to vary its abutment position and the length of thread cut is adjusted by varying the axial position of the discs 14, 15 to determine the point at which they meet the end of the work relatively to the commencement of cut. The work or the die-head may be fed axially. Specifications 405,127 and 412,468 are referred to.

Abstract: 1299491 Electron beam deflecting apparatus RCA CORPORATION 4 March 1970 [7 March 1970] 10341/70 Heading H1D A toroidally wound deflection yoke for providing beam deflection in a multi-beam colour TV tube (e.g. delta gun shadow mask tube) while maintaining substantial convergence of the beams over the raster, comprises an annular core and a pair of orthogonally acting beam deflection windings symmetrically disposed about respective symmetry axes, each wound with substantially constant winding progression, wherein each winding comprises in each quadrant a first portion extending from the axis through a first angular segment and a second winding portion extending from that axis through a second angular segment of different angular extent to the second segment, the angular extensions and winding distributions being selected to produce a deflecting field which also provides convergence of the beams. In Fig. 4, the horizontal and vertical windings are 21a and 21b respectively. The ferrite core 22 may have grooved plastic rings (23), (24) (Fig. 2, for example), the front and rear grooves having a 1 degree and 2 degree separation, respectively, the conductors overlapping at the rear (Fig. 3, not shown), but not at the front of the core (Fig. 5, not shown), the separate horizontal and vertical coil windings being subsequently formed by cutting, peeling and interconnecting appropriate conductors, the interconnections being as indicated in Fig. 6 (not shown) with Fig. 4. Convergence errors may be minimized manipulating only four parameters # 1V , # 2V , # 1H , # 2H , equations being given, constants of which are determined by measuring convergence errors for five winding distributions, or more than five windings to minimize the influence of any measurement error. Matrix equations may be utilized to solve simultaneously for minimum convergence errors existing in more than one direction. Specific distribution angles and core sizes are given using No. 23 copper wire. # 1  and # 2  may be so large as to effect overlapping in three layers and three or more parameters corresponding to one or more additional stairsteps may be used. A red, green, blue phosphor dot screen is instanced.

Title: Novel hydrazine derivatives and a process for the manufacture thereof
IPC: C07D213/82
Filed: 1958-04-01
Abstract: The invention comprises compounds of the formula R1-NH-NH-R2, where R1 is picolinoyl or nicotinoyl, and R2 is aralkyl, and salts thereof. R2 includes monoaryl-alkyl and diaryl-alkyl groups.  These compounds may be prepared by either condensing picolinic acid or nicotinic acid or a salt of either (in the presence of a carbodiimide) or a reactive derivative of either with an aralkylhydrazine, or reacting nicotinic acid hydrazide or picolinic acid hydrazide with an aralkyl carbonyl compound and hydrogenating the resulting hydrazone, or treating the hydrazone with a Grignard compound followed by hydrolysis; and, if required, converting the product into a salt.  The reaction with the carbodiimide (e.g. dicyclohexylcarbodiimide) is preferably carried out at 15-30 DEG  C.; a solvent may be used, such as methylene chloride, chloroform, dioxane, tetrahydrofurane, N,N-dimethylformamide, acetonitrile or water.  Suitable reactive derivatives of picolinic and nicotinic acids are the alkyl esters with 1-6 carbon atoms in the alkyl group, and halides and amides. Where the intermediate hydrazone is hydrogenated this is preferably effected in an inert solvent in the presence of a catalyst such as platinum oxide or palladium/charcoal.  The hydrogenation can be carried out simultaneously with the reaction.  Salts of the bases of the invention are prepared by reacting the base with the acid, preferably in an inert solvent with an excess of the acid. Suitable acids are hydrohalic and mineral acids and tartaric, citric, camphor sulphonic, ethane sulphonic, salicylic, ascorbic maleic and mandelic acids.  Examples describe the preparation of (1) 1-nicotinoyl-2-[21-(p-methylphenyl) - isopropyl] - hydrazine; (2) 1-nicotinoyl - 2 - (21 - phenyl - isopropyl) - hydrazine and its hydrochloride; (3) 1-nicotinoyl-2 - (diphenylmethyl) - hydrazine; (4) 1-nicotinoyl - 2 - (21,21 - diphenylisopropyl) - hydrazine; (5) 1 - picolinoyl - 2 - benzyl - hydrazine and its hydrobromide, phosphate, tartrate and hydrochloride (all by reduction of the corresponding hydrazone); (6) and (7) 1-picolinoyl - 2 - benzylhydrazine and its hydrochloride (by the reaction of benzylhydrazine with picolinic acid or ethyl picolinate).  Other compounds specified are 1-nicotinoyl-2-benzyl-hydrazine, 1 - picolinoyl - 2 - (21 - phenyl - isopropyl) - hydrazine, and 1 - picolinoyl - 2 - (diphenylmethyl)-hydrazine.
